Application filed October 2, 1916. Serial 110.12%,37'2'.

To allevhbm it may concern.

Be t known that '1, JOHN F. HI-ZMENWAY,

a citizen of the United States, residing at New York cit in the countyof New York and State of i cw York, have invented certain new and usefulImprovemcntsai lrcssure-Screws for Clothes-'ringers, of which thefollowing is a specification, reference oeinghad therein to theaccompanying drawing.

This invention relates to certain new and useful improvements, inpressure screws for a of the clothes wringers, the object being toprovide a pressure screw with a semi-oval shaped headhaving recesses toreceive the fingers so that the same can be readily asped by theoperator in ordcrto adjust t e pressure on the ressure rolls without anydanger and slipping thereby overcoming the disadvantages now existing inpressure screws of this character as when the hand becomes soapy and itis attempted to operate the pressure screws on the clothes wringer thehand slips, while with this construction a firm gri is obtained.

Another object o' my invention is to provide a pressure screw which isexceedingly simple and cheap in construction, and one which is providedwith a head of such a shape that the same can be readily grasped by thewhole hand.

Other and further objects and advantages of the invention will behereinafter set forth and the novel features thereof defined by theapiended claims.

in the drawings,

Figure l is' a perspective view of my improved construction of pressurescrew;

Fig. 2 is a detail side elevation of a portion of a clothes \v-ringerpartly in section showing the a 'iplication of my improved constructionof clothes wringcr thereto; and

Fig. 3 is a side elevation partly in section of my improved constrlmtionof pressure SCI'QV- Like numerals of reference refer to like parts inthe several figures of the drawing.

In carrying out my invention I preferably form the pressure screw bycasting the same, but it is, of course, understood that the same can bemilled out of a block, or the stem and which gradually decrease -tionand a series of finger receiving re signature in the presence of twowitncssc head can be formed separately and connected together.

In constructing my screw, as herein shown I provide a semi-oval shapedhead. 1 having a threaded shank J, the outer of the head being providedvi' rooves o in Width and depth toward thcpeint' of the we! so toprovide a smooth surface upon which the hand can be placed, the fingersr nr:

L in the grooves so as to thoroughly g ip s; head in order to turn thescrew.

By providing a-pressure screw of this character to he used in connectionwith a clothes wringer, the operator is able to sp the head andmanipulate the screw to adjust the pressure on the pressure railsWithout any danger of the hand slipping on the pressure screw as itwill-be seen that the hand is in position, the palm rests upon the topscrew and the finger is dropped into the recess so that the head can hegrasped.

I claim:

1. A ressure screw for clothes stringers, comprising a threaded shankhaving a sn cstantially semi-oval shaped head the circumferenceof saidhead being provided with vertically disposed recesses substantially ssemicircular in cross section extending from the ed e of said headtoward the ct thereo said recesses decreasing in width and depth towardthe center of the head forming a substantially smooth central 2. As anew article of manufacture a sure screw for clothes wringers, eon"a'threaded' shank having a snostanta semioval shaped hcadcarriedcircumference of said head being pro; died with radially extendingsnhstantiaiiy circular grooves graduaily decreasing in width and depthfrom the lower edge thereof toward the point of the oral forming aplurality of tapering finger recesses.

In testimony whereof I hereunto atiix my JOHN F. HEMENWAY, WitnessesGnomes W. Renews, G. R. PATCHEN.
